粮食系统的温室气体排放数据大多分散在各个部门，在许多国家仍然无法获得。EDGAR-FOOD是一个全球一致的粮食排放数据库，汇集了1990-2015年国家一级与粮食相关的土地利用和土地利用变化、生产、加工、分销、消费和残留的排放。我们开发了一个新的全球粮食排放数据库。（EDGAR-FOOD）估算温室气体（温室气体; 1990-2015年期间的二氧化碳、甲烷、一氧化二氮、氟化气体）排放量，以全球大气研究排放数据库为基础，并辅之以粮农统计数据库排放数据库中的土地利用/土地利用变化排放。EDGAR-FOOD提供全球食品系统从生产到消费，包括加工，运输和包装的温室气体排放的完整和一致的时间和空间数据库。它针对许多国家缺乏详细数据的问题，提供了对设计有效减缓行动至关重要的粮食系统排放的部门贡献。2015年，全球食品系统的排放量为每年18 Gt CO2当量，占温室气体排放总量的34%。最大的贡献来自农业和土地利用/土地利用变化活动（71%），其余来自供应链活动：零售、运输、消费、燃料生产、废物管理、工业加工和包装。还讨论了粮食系统温室气体排放的时间趋势和区域贡献。
Data on GHG emissions from the food system are mostly scattered across sectors and remain unavailable in many countries. EDGAR-FOOD, a globally consistent food emission database, brings together emissions from food-related land use and land-use change, production, processing, distribution, consumption and residues over 1990-2015 at country level.We have developed a new global food emissions database (EDGAR-FOOD) estimating greenhouse gas (GHG; CO2, CH4, N2O, fluorinated gases) emissions for the years 1990-2015, building on the Emissions Database of Global Atmospheric Research (EDGAR), complemented with land use/land-use change emissions from the FAOSTAT emissions database. EDGAR-FOOD provides a complete and consistent database in time and space of GHG emissions from the global food system, from production to consumption, including processing, transport and packaging. It responds to the lack of detailed data for many countries by providing sectoral contributions to food-system emissions that are essential for the design of effective mitigation actions. In 2015, food-system emissions amounted to 18 Gt CO2 equivalent per year globally, representing 34% of total GHG emissions. The largest contribution came from agriculture and land use/land-use change activities (71%), with the remaining were from supply chain activities: retail, transport, consumption, fuel production, waste management, industrial processes and packaging. Temporal trends and regional contributions of GHG emissions from the food system are also discussed.
